Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To simplify configuration and to miniaturize a device as a whole by detecting the move of source terminal part of an arm member, processing this signal and measuring the diameter of a disk object. SOLUTION: When a motor 10 is rotationally driven, a belt 13 oblique to a passage 12 is turned, and disk objects 33 and 34 are slid and moved through the passage 12 along a side wall 16 to be a reference plane. When the first disk object 33 to move touches a roller 23, an arm 20 is rotated in clockwise direction against a spring 22, and a photosensor 25 is covered with a light shield panel 24. As a result, the length of time for the photosensor 25 to be covered with the light shield panel 24 is made different corresponding to the size of the disk objects 33 and 34, namely, the size of diameter of the disk objects 33 and 34. Therefore, the diameter of the disk objects 33 and 34 to move can be measured by the time length of ON/OFF due to the photosensor 25.  Further, by combining signals proportional to the speed of a means for moving the disk objects 33 and 34, the diameter of the disk objects 33 and 34 can be precisely measured.

Title: Production of optical disk substrate
Inventor: IGARI TOKUO
IPC: G11B7/26
Filed: 1993-05-20
Abstract: PURPOSE:To obtain a high-quality optical disk without defect by allowing a substrate having <=0.05% water content to stand in vacuum of <=0.5Pa for >=30min and then forming a recording film on this substrate. CONSTITUTION:If a recording film made of a rare earth-transition metal amorphous alloy thin film is formed on a condition having >0.05% water content, the recording film is oxidized by the water content in the substrate. This decreases the coercive force which is one of important magnetic characteristics and gives large influence on recording and reproducing characteristics. The vacuum degree is preferably <=0.1Pa. If the optical disk substrate is left in an atmosphere of >=0.5Pa vacuum, the surface of the substrate is contaminated to decrease ByER. This contamination of the substrate is very fine defects of about <=1mum size and easily generates in a wide area of the substrate surface. Not only ByER is decreased by this defect but reproducing errors are produced when the recorded data is reproduced.
